All the new bosses (even the gingerbrat) are level 1. So its basically a 1 hit KO. (New)
Go to Shop > Items for:
Reset Points
50M (Check your gear after using this option. Then sell those items for the coins)
2 level 100 NPC to fight in your team (You can keep purchasing this)
Steps
Download required files above
Extract all the files to your desktop
Open Fiddler
Use your mouse, Drag downloaded files (all the .swf files) into the Autoresponder tab in fiddler
It should look like this. Make sure "Enable auto.." and "Permit pass..." are both ticked. (it should look something like the screenshot. Make sure you drag ALL the files into fiddler)
Just enter Ninja Saga
Just fight those bosses and it's 1 hit KO. If it isn't, you have not replaced the files correctly, because I have tested it. (clear browser cache will definitely help if you have trouble)
Also, all missions are now instant finished.
